Last seen in Season 8, the Nazi necromancers known as the Thule Society are back with a Jurassic Park-esque plot to resurrect Adolf Hitler. Fortunately, the Winchesters are onto their dastardly scheme.

“We believe they may have been in possession of a cursed object of sorts that might have a bit of Hitler’s soul,” star Jared Padalecki previewed during TVLine’s visit to the Supernatural set in Vancouver. “We have to go back and track the Thule and figure out if, in fact, they have succeeded” in reviving the Nazi leader via a 1930s gold pocket watch.

“Hitler’s vessel, thankfully, is gone,” Padalecki says, but the Führer still manages to make an appearance. “It’s fun to see the Supernatural take on what Hitler was really like behind the camera,” the actor adds.
